* minimum hardware requirement 1 server (running OpenSER or Asterisk or
(the older) OpenH323 GK)
* for clients, you'd need either a IPPhone, or a PC with a sound card
running a softphone (software ip phone, which may support the following:
H323, SIP (most common), IAX, MGCP, etc.)

yes, but you'd be setting it up as a peer-peer, which means user's would
need to dial the phone's ip address. better to use a server which will
act as a gateway/router/register (depending on which protocol you'll
use, I'd recommend SIP).

if by free you mean opensource, then yes. there are lots of opensource
components you can use to build your voip infrastructure.

the easiest, imho, is to use asterisk or [EMAIL PROTECTED] once you get
comfortable with the voip concepts, explore the other projects. But for
most internal usage, asterisk would suffice. It is designed to be a
soft-pbx which is what you most likely need.
for a start, setup asterisk (or [EMAIL PROTECTED]) with some xten lite as
clients. play with it and see if that's what you need. you can buy the
voip hardware after you've setup your first asterisk, not before.
